Complete the CLI args

[liangchenye]

Now we have CLI spec defined, we need to complete the 'args' of 'create/kill' in 'validation/util/container' .

• add lifecycle testing function
  working on Fix #556  #557
• create with 'pid-file'
  working on Fix #556  #557
• create with 'socket'
  I don't have an idea to implement it now.
• kill with 'signal'
  'runc' does not follow this yet or we can implement it by writing a process which track the kill signal
